Valve Spring Manufacturers

With over 70 years of engineering expertise, we have become one of the UK’s most respected valve spring manufacturers. We specialise in producing high-performance, ISO 9001-accredited valve springs for industries that demand reliability and precision. From tailored designs to dependable stock supply, we provide solutions built to last. 

Bespoke & Stock Valve Spring Suppliers

We produce both custom-designed and standard valve springs, ensuring your component performs reliably across a wide range of environments. We frequently work with clients who require anything from a single prototype to a bulk order for production, our manufacturing facilities and engineers can deliver quickly and precisely. 

Valve springs are fundamental to valve operation, ensuring they return to the closed position and remain properly sealed. They maintain steady tension, prevent valve float, and protect against leakage or operational breakdowns.

Why Choose Custom Valve Springs?

Custom valve springs are especially valuable for high-load applications where pressure consistency is important, extreme environments involving heat, vibration or corrosion exposure, and safety systems requiring fast and reliable valve closure.  

Valve springs must withstand high pressures, temperatures, and constant use, so material selection is crucial. Common materials include: 

  • Oil Hardened Spring Steel: A high-strength oil-hardened valve spring steel made for highly stressed springs. This has an operating temperature of -60 to +250°C. Variations of this material type include Oteva 60, Stato 70, and Oteva 70.  
  • Stainless Steel: Offers excellent corrosion resistance, making it ideal for harsh environments.​ 
  • Inconel: A nickel-based alloy resistant to intense heat and corrosion, suitable for high-temperature environments.​ 

We manufacture valve springs in a range of materials to match the demands of different industries, ensuring long-lasting performance. 

Stock Valve Spring Solutions

In addition to custom solutions, our status as a member of the internationally renowned Lesjöfors Group means we are able to provide standard stock valve springs.

Valve Springs in the Oil & Gas Industry

In the oil and gas sector, valve springs play a critical role in controlling the flow of oil, gas, and other fluids. 

  • Flow Control and Pressure Regulation: Valve springs help regulate the opening and closing of valves in pipelines and refining equipment. They maintain consistent pressure and prevent leaks, which is essential for safety and efficiency. 
  • Drilling and Wellhead Equipment: Drilling operations place immense stress on equipment. Valve springs in wellhead safety valves and hydraulic systems absorb shock and ensure smooth function under extreme conditions. 
  • Emergency Shut-Off and Safety Valves: In high-risk environments, safety valves rely on precision-engineered springs to close rapidly in an emergency. These springs help prevent blowouts, equipment damage, and environmental hazards.

Frequently asked questions

What Are Valve Springs?

A valve spring is designed to return a valve to its closed position after it has been opened. They maintain the correct tension on the valve, ensuring smooth operation and preventing failure. 

The right choice depends on load, operating environment, and required lifespan. Stainless steel covers most general applications, while Inconel, titanium, and Hastelloy perform best in extreme or corrosive settings.  

  • Automotive:In car engines, valve springs manage the timing and movement of the intake and exhaust valves, optimising air and fuel flow for performance, efficiency, and emissions control.​
  • Aerospace:They regulate fuel and hydraulic systems in aircraft, ensuring proper pressure and flow for essential functions like engine fuel supply and hydraulic operations.
  • Industrial Machinery:Valve springs ensure smooth operation in hydraulic and pneumatic systems by controlling fluid flow.
  • Medical Devices: They provide precise valve control in infusion pumps and respirators, ensuring accurate fluid delivery for patient safety and effective treatment.​ 
  • Oil & Gas: In the oil and gas sector, valve springs play a critical role in controlling the flow of oil, gas, and other fluids. They work in areas such as flow control, pressure regulation, drilling and wellhead equipment, emergency shut-off and safety valves.  

Yes, all of our components are certified under ISO 9001:2015, and we conduct rigorous quality control across all our processes.
